    I have Cisco EPC 3928 modem. Mac clone/change does not exist in the router web interface. It's cable internet so there's a cable that goes straight in the modem. So I am stuck behind a router and can't change it's mac.

    Is my only option buying cable modem and plugging it direct in pc?

    Just go the easy way and get a router with mac address clone feature. Connect your modem and computers to it, clone your mac and you're done.

    As far as I know many TP-LINK routers support this feature out of the box. If you need more advanced settings, you should be looking at dd-wrt firmware, but it's going to be overkill if all you need is to change your mac.

    Can't you just spoof the MAC with a software or even within the OS? http://www.online-tech-tips.com/computer-tips/how-to-change-mac-address/

    A router would be a better option, that works for sure. Not sure if there is a price difference between a basic router and a modem. I'm using the same wifi router for 10 years now. Linkysys WRT54GL, it runs on Linux, custom firmware can be installed on it, so it's highly customizable. It's still not the cheapest option though.

    If you have a faster internet connection and opt-in for a wireless router, besides the MAC address changing capability, you should pay attention to another thing: the router speed. The older routers are 54 Mbps and if you have an internet connection faster than half of that (wireless is half-duplex), you won't be able to use the connection to its full potential, so you might want a 150, 300 MBps or 1 Gbps router.

    I am behind a router so router is communicating with isp, not my network card, then the data is transfered to my pc, so changing mac won't work if router doesn't allow it. I currently have that wireless router you're talking about, it just doesn't have mac change/clone option.
